A Comparative Study Between M30 and M92 : M92 Is A Merger Remnant With A Large Helium Enhancement

Jae-Woo Lee

We perform a comparative study of the ex--situ second--parameter pair globular clusters (GCs) M30 and M92, having similar metallicities but different horizontal branch morphologies…

WALLABY Pilot Survey: the Potential Polar Ring Galaxies NGC~4632 and NGC~6156

N. Deg, R. Palleske, K. Spekkens +24

We report on the discovery of two potential polar ring galaxies (PRGs) in the WALLABY Pilot Data Release 1 (PDR1). These untargetted detections, cross-matched to NGC 4632 and NGC 6…

Carbon Abundance of Globular Cluster M22 (NGC 6656) and the Surface Carbon Depletion Rates of the Milky Way Globular Clusters

Jae-Woo Lee

It is well known that metal-poor red giant branch (RGB) stars show variations in some elemental abundances, including carbon, due to the internal mixing accompanied by their own in…

M92 (NGC~6341) Is a Metal-Complex Globular Cluster with an Atypical Primordial Population

Jae-Woo Lee

We present a multiple stellar population study of the metal-poor globular cluster (GC) M92 (NGC 6341), which is long known for the substantial metallicity dispersion, using our own…

Breakdown of the Newton-Einstein Standard Gravity at Low Acceleration in Internal Dynamics of Wide Binary Stars

Kyu-Hyun Chae

A gravitational anomaly is found at weak gravitational acceleration m s from analyses of the dynamics of wide binary stars selected from the Gaia DR3…

WALLABY Pilot Survey: Hydra Cluster Galaxies UV and HI morphometrics

Benne W. Holwerda, Frank Bigiel, Albert Bosma +16

Galaxy morphology in atomic hydrogen (HI) and in the ultra-violet (UV) are closely linked. This has motivated their combined use to quantify morphology over the full H i disk for b…

FEASTS: IGM cooling triggered by tidal interactions through the diffuse HI phase around NGC 4631

Jing Wang, Dong Yang, Se-Heon Oh +14

We use the single-dish radio telescope FAST to map the HI in the tidally interacting NGC 4631 group with a resolution of 3.24 (7 kpc), reaching a 5- column density limit of $…
